A new study finds that home colon cancer screening tests may be as effective as a colonoscopy at preventing cancer death. 'WH' talked to experts to explain.
The Food and Drug Administration (FDA) has recently approved a blood test screening for colorectal cancer that has an over 83% success rate at detecting the presence of this form of cancer.
The test is designed to detect tiny traces of blood which may be a warning sign for colorectal cancers.The big picture study, which was published in Annals of Internal Medicine, examined the data ...
The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
Colorectal cancer screening programmes are widespread in Europe. In England, adults are screened biennially between ages 60–74, [32] and recently extended to ages 50–74. They are screened via fecal immunochemical test (FIT), that is sent home to the individual. However the program currently has a high threshold in which a big proportion of ...
Indeed, colorectal cancer is one of the only cancers that can be prevented with screening, and colonoscopy is, by far, the most accurate way to detect it. But screening rates are extraordinarily low.
The fecal sample is obtained by catching the stool and transferring a sample with an applicator. Digital rectal examination specimens are also used but this method is discouraged for colorectal cancer screening due to very poor performance characteristics.
